Hi ST,I have an custom board using the ISM330DLC but I'm having difficulty configuring it's primary bus for 3-wire SPI operation.According to the ISM330DLC datasheet register CTRL3_C (0x12) must set to 0xC for 3-wire primary bus SPI mode to be enable...

If the ISM330DLC is connected to two separate dedicated SPI buses (i.e. no other SPI slaves on the bus) can the CS and OCS_Aux pins be connected to ground or do they have to be controlled by their respective SPI masters?

Posted on September 13, 2017 at 21:23I’m trying to implement a simple data-logger that runs on a bespoke STM32F2xx board which is capable of storing data to an SD-Card (SDIO 4-bit + DMA) and will enable windows to copy the stored data from the SD-...
